Fix for Error : Component “sysinfo.ocx’ or one of its dependencies not correctly registered (after Windows Update)

On March 31, 2017, Microsoft released a security update for Windows Defender and Microsoft Security Essentials. The update inadvertently flags the common system OCX file “sysinfo.ocx” as infected by the virus Worm:Win32/Bluber.A. This is a false positive, and Microsoft has subsequently released a fix for the update.

To fix the error, please follow these instructions:
1) Open Windows Defender (or Microsoft Security Essentials, depending on your operating system)
2) Click on the History tab
3) Find the quarantined file “Worm:Win32/Bluber.A” and check the box, and click “RESTORE”
4) Click on the Update tab, and select the Update button to download the latest release of Windows Defender or Microsoft Security Essentials
